I cannot tell if my return was filed ?

i did not receive a confirmation from CRA,  I asked 5 days ago how to tell if my e-file went through, I cannot follow the instructions on this system it states in the upper right area of turbo tax select "find" I CANNOT FIND find? So I redid my taxes using same system when I went to e-file it said that I was already filed.For something so easy to do its really hard to check weather or not you e-filed correctly, it was my 1st time using this system, I just want a confirmation number that the government has my file. Any help would be greatly appreciated.
